Patent CA-2460138-C (CA)
Title: Catalyst and process for decomposing carbonyl sulfide and hydrogen cyanide
Inventor: EGAMI KAZUTAKA
IPC: B01J35/10
Filed: 2002-10-30
Granted: 2009-09-22
Abstract: A solution of a chromium compound is impregnated into a silica-alumina carrier made of alumina and containing 1 to 5 weight % of silica relative to the weight of the carrier, thereby to obtain a decomposing catalyst carrying 10 to 15 weight % of chromium oxide relative to the weight of the catalyst in terms of Cr2O3. By contacting mixed gas obtained through partial oxidation of heavy oil and/or coal with the decomposing catalyst, COS and HCN contained in the mixed gas are decomposed/removed. In this case, transition of alumina into boehmite can be suppressed owing to coexistence of silica and chromium oxide, so that COS and HCN can be decomposed by highly active catalytic reactions over a long time.

Abstract: The de-inking procedure consists of circulating the pulp in a flotation cell comprising a chamber (2) with a vertical axis in which the pulp can move downwards from top to bottom, passing through a series of stages (E1...En), in each of which bubbles (13) introduced in the lower part of the chamber pass through it. The bubbles reach the top of the chamber in the form of a foam (5) carrying particles of non-soluble materials, the foam being removed at the top while the de-inked pulp is drawn off at the bottom. In each of the aforementioned stages the rising bubbles follow the under-surface of a spiral guide (12) to reach the passages taking them to the higher levels. In addition, the speed of the pulp is accelerated at the passage entrances by a progressive reduction in the passages' cross-section to draw the bubbles through and mix them with the pulp.

Granted: 2006-12-19
Abstract: La présente invention concerne un appareil conçu pour détecter des données à partir d'un capteur optique à distance (16). La fréquence de cet appareil est stabilisée au moyen d'un équilibrage des sorties de filtres à bande étroite (28, 30), espacés autour d'une fréquence souhaitée (36) située aux environs des points bas 3dB (40) d'une source lumineuse à large bande (10), en utilisant une commande de tension, une commande de courant ou une commande de température afin de faire varier la fréquence de la source lumineuse à large bande (10). On peut utiliser la différence entre les sorties traversant les deux filtres à bande étroite (28, 30) afin de piloter un amplificateur (48), en vue de corriger la fréquence de la source lumineuse à large bande. Les sorties traversant les deux filtres à bande étroite (28, 30) peuvent être converties (52) en nombres binaires et être transmises à un microprocesseur (56) qui sert à piloter l'amplificateur (48) par l'intermédiaire d'une conversion analogique (60).

Title: Cubic logic toy
Inventor: VERDES PANAYOTIS
IPC: A63F9/08
Filed: 2004-05-13
Granted: 2012-02-21
Abstract: This is an invention that concerns the construction of three-dimensional logic toys, which have the shape of a normal solid, substantially cubic in shape, and N number of layers in each direction of the three-dimensional rectangular Cartesian coordinate system, said layers consisting of smaller separate pieces. Their sides that form part of the solid~s external surface are substantially cubic. The said pieces can rotate in layers around the three-dimensional axes of the coordinates; their visible rectangular surfaces can be colored or they can bare shapes, letters or numbers. The construction is based on the configuration of the internal surfaces of the separate pieces using planar, spherical and mainly right conical surfaces, coaxial to the semi-axis of the coordinates, the number of which is .kappa. per semi-axis. The advantage of this construction is that by the use of these .kappa. conical surfaces per semi-axis, two solids arise each time; the first has an even (N=2.kappa.) number of layers per direction visible to the user, whereas the second has the next odd (N=2.kappa.+1) number of visible layers per direction.  As a result, by using a unified method and way of construction, for the values of .kappa. from 1 to 5, we can produce in total eleven logic toys whose shape is a normal geometric solid, substantially cubic in shape. These solids are the Cubic Logic Toys No N, where N can take values from N=2 to N=11. The invention became possible after we have solved the problem of connecting the corner piece with the interior of the cube, so that it can be self -contained, can rotate unobstructed around the axes of the three-dimensional rectangular Cartesian coordinate system and, at the same time, can be protected from being dismantled. This invention is unified and its advantage is that, with a new different internal configuration, we can construct - apart from the already known cubes 2x2x2, 3x3x3, 4x4x4, 5x5x5 which have already been constructed in many different ways and by different people - the next cubes from N=6 up to N=11. Finally, the most important advantage is that it eliminates the operational disadvantages that the already existing cubes have, except for the Rubik cube, i.e. 3x3x3.
